TIME-STAMP.

Specification of Letters Patent:

Patented Mar. 29, 1921.

Application filed March 10, 1920. senn No. 364,865.

Be it known that I, REINHQLD SCHMIDT, citizen of the German Republic residing at Diisseldorf-Oberkassel, Germany, have in vented certain new and useful improvements in Time-Stamps, of which the following is a specification. V

This invention relates to a time stamp with type wheels which are adjusted with respect to stepped disks by a forward movement of rails having abutments, said stepped wheels being driven by a clock-work. Time stamps of this kind are known; in those contrivances the stamp proper and the clockwork, as well as the stepped disks, are arranged in a common casing sothat the handling of such a stamp is rather troublesome. It is also known to introduce thepaper to be stamped, 2'. e. a strip of paper, into the stamp and to efiect the stamping by depressing a lever, butsuch devices are restricted to strips, whereas it is often necessary also to stamp larger pieces of paper, such as This is made possible byv my improvements the essential feature of. which is the separation of the time stamp proper from' the clock-work with its stepped disks, the arrangement being such that the stamp proper need only be shoved into the clockwork casing in order to be properly adjusted. The time stamp thus constructed is very convenient and handy and may be employed for stamping all kinds of articles inv that it is employed like an ordinary hand stamp as generally known.

In order to make my invention more clear, I refer to the accompanying drawing,

in which similar letters denote similar parts throughout the several views, and in which: Figure 1 is a vertical section through time stamp constructed according to my invention; p

Fig. 2 is also a vertical section taken at right angles to that of Fig. 1;

'Fig. 3 is a horizontalsection on line A-B of Fig. 1; I

Fig. 4: is a vertical section through the stamp'part indicated by the line CD of Fig. 1.

Fig. 5 is also a vertical section through the stamp part indicated by the line EF of hag. l, and

Big. 6 is an enlarged detail view otcer- I tain slides comprised ill tile mechanism and the parts immediately associated therewith.

The clock-work 1 is arranged in the casing 2 ano drives in known manner by means of its minute shaft 3 the shaft 6 by the mediation of a spring 5 attached to a disk 4, and by the mediation of a crank pin 7. The shaft 6 supports three stepped disks, viz. the disk 8 for the unit minutes, the disk 9 for the tens minutes,. and the disk 10 for the hours. The stepped disks 8 and 9 are firmly connected with the shaf 6 and rotate with the same speed as the minute hand of a V clock, that is to say, they make one complete rotation in one hour. The stepped disk 10, however, sits loosely upon the shaft 6 and is driven by the mediation of the c0g wheel pairs 11 and 12 with a speed correspending to that of the hour hand of a clock. The disk 8 is provided with six equallugs,

' which when the respective slide is depressed contacts with the respective stepaed disk, that 1s to say, the lug 18 of the slide 14 con .tacts with thedisk 8 the lug 18 of the slide 15 contacts-with the disk 9; and the lug 18 of the slide 16 contacts with the disk 10..

The slides 14. 15, 16 have upwardly extending elongated fingers 19, 20, 21 which are different in length corresponding to the greatest possible displacement of said slides. The casing 2 has an upward extension 22 which incloses the upper ends of the slides 14, 15, 1 i. 6., the fingers 19, 20, 21.

The timestainp proper, although involved in a certain relative arrangement with respect to the combination and arrangement of parts above described, is in itself a separate combination and arrangement of parts, which is supported by the extension 22 01 tlie'casing 2. 23- is the casing of the time stamp proper; it has a handle-2e; its lower end extends into the part 22. Said lower end hasupon an-axle 25 three type wheels 26;, 2'7, 28 which are loosely rotatableupon' said'axle'. 26 is the type wheel forsingle minutes,'27 is the type wheel for tensiof mmutes. and 28 is the type wheel for hours.

Each typewheel is connected with a cog;

wheel 29 which meshes with a large cogwheel 30 that is located above it and 1s firmly connected w th a small cog-wheel .32;

these two cog wheels 3O and'32 are loosely rotatable upon ashaft 33, Each otthe small cogqwheels 32 meshes witha rack 3% which is attached to a slide 35. There are thus-three such slides. Each of them has four slots 36 throu h whichextend four bolts??? 0 which the slides are 'uided and each has its lower end a lug 38 which extends into a holeproi 'ided in thebottom of the casing 23. These lugs and holes are so arranged that when the time stamp, or its casing 23 respectively,-is sho'yed into the elongation 22 of the clock-work casing 2, each of the fingers .19, 20, 21 enters one of the saidholes and contacts with the respectivelug"38 of the respectiyeslide 39 are helical springs which constzuitly Jtend'to pull the slides downward, and 40 are. vertical slldes which are" also guided by the bolts 37 and have each a large cut-out embracing the respective cog-wheel 30' A- the lower end of each cut-out is an upwardly extending tooth 41 which takes into therespect ve cog-wheel 29 when the respective slide? moves upward.

The threeslidesflO are connected at their. upper ends by a cross-piece 65 ,and by this cross-piece with a bar which extends is a sprlng con through the handle 24. stantly tending to force the bar 42 upward,

' and is a knob forming the upper end of saidbarp Theeifectof the spring is also to make the teeth ll engage the cog-wheels 29, 1f the'knob L4: 1s not depressed.

Between each two slidesO are two small Yrolls- 45 which are adapted to glide upon oblique surfaces ofa horizontal slide: 46

which has a pin el-7 against which is pulled a bell-crank lever 48 by means of a spring 4:9. The horizontal arin, ofthe bell-crank lever llextends a little out of the casing When introducing the casing 23 into the casing 22, said'horizontal lever arm is moved inward contacting the curved-sur- COl'Cllll cording face )i'ovided at the uoncr'side of the P v .1. i 1 0 central. opening or the he. of the casing, 22,

and by that movement of the said .leVerarin the horizontal slide islateraly dis slaced 1e 'niediatioii of the other m 01" the said bell-cranlrleverand the pin 47. Hereby the slides' 4 :0 which are connected by the cross-piece moved downwarr isothat the teeth l'leaye the cog-wheels 29. e

The handle 241 is rotatable upon the casing 23 and has at its inner-fend a disk to which is attached a downwardly extending rail 52 having at its lower end; a bolt which is held in an elastically yielding bearing. 54 is a spring which is afiixed at one end to the dish 51 and at the other end to the casing; 23 and which tends to turn said disk and the rail- 52 in sucha direction that one end or the upperslot 55 which is provided in the rail 52 contacts with a stationary horizontal bolt. 56 extending throughthe casing 23, whereas one end of the lower slot 55 also provi ed in the rail contacts with theshai t't I At tief nner side of thecas ng 22 is a vertical slot- 57 which hasseycral notcheshS another slot '60, extends parallel to said slot 7 57; .59 isaconnection'at the lower ends of said slots. v I

When the casing 23 is introducedinto the casing 22', then the teeth 41 are disengaged from the cog-wheels 29 by means 01" the lever 48 sothat the springs 39 are capable.

of'pulling' t-he'slides 35,with the racks 34 into the lowest position whereby the type disks are adjusted to zero 7 Furthermore,

the bolt 53engages atthesaine time" the first notch 58* so that the time stamp proper cannot hedrawn'out 01"" the casing 2, but can,

only be further depres ed, into its deepest? position in which bya slight rotation of the-handle 25% the bolt is moved into the vertical slot" GOthroughl'tne connecting slot' 59's 'ter whichtie stamp "is freeto be with-' [drawn from the casing 22.

@On introducing the stamp proper into the (-asm the fihgers '19, 20.; 21 and depress the slides 14-, 1s and sion, whichlatter thus-tend to return the slides into their former position. )wing' to this downward movement or theslides, the lugs 18 ofthe same come into engagement w'ththe stepped disks; 8, 9, 10 and during the further clownwarcl;inove1nent of the StlillPtllQ now stationary slides 14c, 15, 16 or more; precisely, their-fingers. 19, 20, 21 shove the slides 35 of the stamp upward, whercl atthe respectivevrnoment, that is to say, ac-

that moveriienttakes place.

put the springs 6'? under. ten- 2, 1.. e.,-1nto lts'neck 22, and pressing it down into the same, the lugs 38 push upon the type wheels are adjusted a-c- ..o the position of the stepped disks to the hour and minute in which \Vhen the stamp has arrived in its lowest position, in which-it is possible-to move the bolt through-the connecting slot 59, then the later 4:8 getsbehind a ledge 61 provided in the neck 22 of the casing Zinconsequence of which the teeth a l engage the cog-wheels whereby the type wheels are secured 'in'their adjusted position.

when the stamp is drrwn outoi the neck 22,

the type-wheels remainin the position which type wheels would remainin their adjusted position and a wrong time would be stamped when the stamp is used over again.

In the bottom or" the casing 2 is a slot 63, by of which the clock-work ;may be adjusted by the action of the cog-wheel 12. Turning the clock-work back is prevented by a pawl 64-.
